BRAKE-BEAM HANGER.

To all whom it may concern.-

Be it kno-wn that 1, WILLIAM F. CREMEAN a citizen of the United States, residing at Frankfort, in thelcounty of Clinton and State of Indiana, have invented certain new and useful Improvements in Brake-Beam Hangers, of which the following is a spec1- fication.

My invention relates to a new and useful improvement in brake beam hangers and particularly to a hanger wherein it will be impossible for the pin to become accidentally lost or work out of the hanger when the same is in service.

As is well known a good many derailments are caused by the pins working out of the brake hangers, permitting the brake beam to dro and the brake head and shoes to fall on or the wheels.

An object of my invention therefore is to provide a special form of pin and hanger arms wherein it will be impossible for the pins to work out of the hanger arms while the same is in service.

Another object of m invention is to so construct the pins an hanger that both arms of the hanger are identical and may be made from the same mold when casted, it only being necessary to invert one arm with relation to the other.

Still another object of my invention is to utilize two pins that are also identical, so that although four members make up the entire hanger which includes the pins and hanger arms only two different parts are used, the other two being duplicates.

Referring now to the drawings forming a part hereof,

Figure 1 is a sideelevation of my hanger applied to a standard brake head;

Fig. 2 is a front elevation of the hanger;

Fig. 3. is a front elevation of the hanger arm;

Fig. 4 is a vertical section of the same;

Fig. 5 is a detail view of the pin, and

Fig. 6 is an end view of the same.

Referring first to Fig. 1 there is shown an ordinary brake head 1, the head forming no art of the invention, and a section of the Brake beam 2. Also a bracket 3 is shown to which the upper part of the hanger, now to be explained, is secured.

Referring now to Figs. 2, 3 and 4, it will be seen that the hanger comprises two hanger arms 4 and 5 and two pins 6 and 7 These'arms 4 and 5 are absolutely identi- Specification of Letters Patent.

cal in construction but oppositely arranged and one inverted with respect to the other.

The pins 6 and 7 are also both of the same construction but one is inserted through the hanger arm 4, while the other is inserted through the hanger arm 5.

The hanger arm 4 or 5 is preferably a cast article and may be of malleable iron or steel, and is provided with a strengthening rib 8 extending practically throughout its length and widened out at both ends of the hanger arm to form the lugs or projections 9 and 10.

i The lug or projection 9 is countersunk or cut out forming a square recess 11 for the reception of the square head 12 of the pin 6, and the opening 13 registering with the recess 11 is circularfor the receptionof the shank of the pin. Therefore when the pin is inserted in the opening 13 the head 12 will rest in the recess 11 and cannot turn in said openlng.

The lower. portion of the hanger arm is slightly different, a circular opening 14 being formed in the lug 10 but having a projection 15 extending across the lower portion of said opening, said portion 15 of course being integral with the hanger arm.

Referring now to the pin 6 it is seen that it consists of. the head 12, and the shank 16, the outer end of which is first slightly reduced as at 17 and then has the protruding lip 18, which is semi-circular, and the distance between the end of the shank 1 6 and the lip 18, or in other words the width of the reduced portion .17, is such that the lip 18 may pass over the outer surface of the projection 15 when the pin is in its locked position.

The hanger is assembled as follows: First the hanger arm 4 is held with the recessed portion 11 as forming the top end, and the pin '6 inserted so that the head 12 will fit within the square recess 11, making sure however that the .lip 18 on the other end is pointing directly upwardly as shown in Fig. 2, and the pin then passed through the bracket 3..

Another one of the arms is then taken and first turned, end for end with respect to the .first one; it is then turned upwardly 90, or at right angles to the arm 4, and the end of the pin 6 passed through the opening '14 and then turned downwardly occupying the position shown in Fig. 2, the lip 18 contacting with the projection 15 and thereby holdingthe two arms together.

It is impossible for the pin to come out unless the arm 5 is first raised again to an angle of 90.

To put the lower pin 7 in place it is first necessary that the lower ends of the hanger arms be pressed slightly together, which is made possible by having the diameters of the openings 13 and 14: slightly larger than the diameter ofthe pin 6. After these arms are forced inwardly at their lower ends, another pin 7 is inserted through the opening 13, in the arm 5, but not so far that the head will seat in the reces's 11, as first it is necessary to turn the pin until the lip 18 will pass behind the projection 15 and then the arms again pulled apart, seating the head 12 in the square recess 11, and of course after the brake head is inserted into place the lower ends of the arms 4: and 5 can not possibly come together, thereby assuring a locked hanger wherein the pins can not possibly work out or be lost in service.

From. the foregoing it will be seen that the hanger consists of but twoarms, one the duplicate of the other and two pins of the same kind, making'the hanger one that is relatively cheap to manufacture and one that is easily assembled. Also there is no danger of either pin dropping: out to thereby drop the brake beam and heads.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

" one opening for restraining a pinagainst turning movement in the opening, and means located on the arm adjacent the other opening forrestraining' a pin against sliding movement in said opening.

2. A brake beam hanger comprising, two hanger arms, both of said arms being identical inform but one inverted with respect to the other when in their set position, openings provided near the opposite ends of said arms, one of said openings being partly obstructed, and means passing through the openings in said arms and looking with the obstructing portions. I

3. A brake beam hanger comprising two arms identicalin form and one inverted with-respect to the other when in their set position, openings near the upper and lower ends of said arms, a recessed portion registering with one of said openings and said recesses being angular in shape,*the other opening in said arms having a projection across a portion of the'face, and a pin pro vided with an angularly-shaped head adapted to fit within said recessed portions and the endof said pin provided with a lip to pass over the projections on the face of said openings.

4. A brake beam hanger comprising two and a second'pinadapted to pass'through hanger arms identical in form and arranged tion; and a lip thereon adapted to pass through openings formed in said arms, one of said hanger arms to be positioned at right angles to the ot-her when one of the pins is firstplaced in position and then to be swung downwardly to lock the said arms in their set position, and a second pin adapted to be passed through openings formed in the lower ends of said arms to thereby retain the hanger in its set position.

5. A brake'beam hanger-comprising two hanger arms both of said arms being identical in form but one inverted with respect to the other, an opening formed near the upper and lower ends of said arms, aprojection across one of said openings in each arm and a pin adapted to pass'th'rough the openings in the u per ends of said arms,. one of said arms being first turned to an angular position and then swung downwardly to lock said arms with .respect to each other,
